Description

本発明は吸収性物品帯状体の裁断装置に関する。   The present invention relates to a cutting device for absorbent article strips.

互いにほぼ平行な回転軸線回りに互いに逆方向に回転するカッタロール及びアンビルロールを具備し、これらカッタロールとアンビルロールとの間に供給された吸収性物品帯状体がカッタロールに設けられた刃により製品部分及びトリムに裁断される裁断装置であって、カッタロールを、トリムを一時的に保持することが可能な保持ロールから構成し、保持ロールは、その周面に形成された周面ポートと、その側面に形成された側面ポートと、これら周面ポート及び側面ポートを互いに連結する連通路とを備え、負圧源に接続された負圧室を備えた負圧マニホルドを具備し、負圧マニホルドはその側面に、負圧室に連通する負圧ポートを備え、負圧マニホルドの側面が保持ロールの側面に対面するように負圧マニホルドを固定し、保持ロールが回転することによって保持ロールの側面ポートと負圧ポートとの連通及び遮断が切り換えられ、保持ロールの側面ポートが負圧ポートに連通すると保持ロールの周面ポートに負圧が印加されてトリムが保持ロールに保持される、裁断装置が公知である（特許文献１参照）。   A cutter roll and an anvil roll that rotate in directions opposite to each other around rotation axes that are substantially parallel to each other, and an absorbent article strip supplied between the cutter roll and the anvil roll is provided by a blade provided on the cutter roll. A cutting device for cutting a product part and a trim, wherein the cutter roll is constituted by a holding roll capable of temporarily holding the trim, and the holding roll includes a peripheral surface port formed on a peripheral surface thereof. A negative pressure manifold having a negative pressure chamber having a negative pressure chamber connected to a negative pressure source, and having a side port formed on a side surface thereof, a communication path connecting the peripheral surface port and the side surface port to each other. The manifold has a negative pressure port on its side that communicates with the negative pressure chamber. The negative pressure manifold is fixed so that the side of the negative pressure manifold faces the side of the holding roll. By rotating, the communication between the side port of the holding roll and the negative pressure port is switched, and when the side port of the holding roll communicates with the negative pressure port, negative pressure is applied to the peripheral port of the holding roll and the trim is held. A cutting device held by a roll is known (see Patent Document 1).

この裁断装置では、保持ロールの側面と負圧マニホルドの側面との間には摺動性を考慮して、パッキンのような封止手段が設けられる。   In this cutting apparatus, sealing means such as packing is provided between the side surface of the holding roll and the side surface of the negative pressure manifold in consideration of slidability.

特開２００８−２３７７９６号公報JP 2008-237796 A

しかしながら、保持ロールすなわちカッタロールは封止手段と接触しながら高速回転するので、摩擦熱が生じ、カッタロールがこの摩擦熱により次第に熱膨張して変形するおそれがある。カッタロールが変形すると、帯状体を十分に裁断できないという裁断不良が生じるおそれがある。裁断不良をなくすためにカッタロールとアンビルロールとの接触圧を高めると、今度は、カッタロールの刃の寿命が著しく短縮されるおそれがある。   However, since the holding roll, that is, the cutter roll, rotates at high speed while being in contact with the sealing means, frictional heat is generated, and the cutter roll may be gradually expanded due to the frictional heat and deformed. When the cutter roll is deformed, there is a possibility that a cutting defect that the band-shaped body cannot be sufficiently cut may occur. If the contact pressure between the cutter roll and the anvil roll is increased in order to eliminate cutting defects, the cutter roll blade life may be significantly shortened.

前記課題を解決するために本発明によれば、互いにほぼ平行な回転軸線回りに互いに逆方向に回転するカッタロール及びアンビルロールを具備し、これらカッタロールとアンビルロールとの間に供給された吸収性物品帯状体がカッタロールに設けられた刃により複数の裁断済み部分に裁断される裁断装置であって、カッタロール及びアンビルロールの一方又は両方を、裁断済み部分を一時的に保持することが可能な保持ロールから構成し、該保持ロールは、その周面に形成された周面ポートと、その一側面に形成された側面ポートと、これら周面ポート及び側面ポートを互いに連結する連通路とを備え、正圧源に接続された正圧室及び負圧源に接続された負圧室を備えた正負圧マニホルドを具備し、該正負圧マニホルドはその一側面に、正圧室に連通する正圧ポート及び負圧室に連通する負圧ポートを備え、正負圧マニホルドの一側面が保持ロールの一側面に対面するように正負圧マニホルドを固定し、保持ロールが回転することによって保持ロールの側面ポートと負圧ポート及び正圧ポートとの連通及び遮断が切り換えられ、保持ロールの側面ポートが負圧ポートに連通すると保持ロールの周面ポートに負圧が印加されて裁断済み部分が保持ロールに保持され、保持ロールの側面ポートが正圧ポートに連通すると保持ロールの周面ポートに正圧が印加されて保持されている裁断済み部分が保持ロールから離脱され、互いに対面する保持ロールの一側面と正負圧マニホルドの一側面との間にわずかばかりの間隙が設けられている裁断装置が提供される。   In order to solve the above-described problems, according to the present invention, a cutter roll and an anvil roll that rotate in directions opposite to each other around rotation axes that are substantially parallel to each other are provided, and an absorption supplied between the cutter roll and the anvil roll. A cutting device in which a strip of a property article is cut into a plurality of cut portions by a blade provided on the cutter roll, wherein one or both of the cutter roll and the anvil roll may temporarily hold the cut portion. The holding roll includes a peripheral port formed on a peripheral surface thereof, a side port formed on one side surface thereof, and a communication path that connects the peripheral surface port and the side port to each other. And a positive / negative pressure manifold having a positive pressure chamber connected to the positive pressure source and a negative pressure chamber connected to the negative pressure source, and the positive / negative pressure manifold has a positive pressure on one side thereof. A positive pressure port communicating with the negative pressure port and a negative pressure port communicating with the negative pressure chamber, the positive and negative pressure manifolds are fixed so that one side of the positive and negative pressure manifold faces one side of the holding roll, and the holding roll rotates. The communication between the side port of the holding roll, the negative pressure port, and the positive pressure port is switched, and when the side port of the holding roll communicates with the negative pressure port, negative pressure is applied to the peripheral port of the holding roll and the part has been cut Is held by the holding roll, and when the side port of the holding roll communicates with the positive pressure port, the cut portions that are held by applying positive pressure to the peripheral port of the holding roll are separated from the holding roll and face each other. A cutting device is provided in which a slight gap is provided between one side of the roll and one side of the positive and negative pressure manifold.

保持ロールの熱膨張に起因する裁断不良を抑制することができる。   Cutting defects caused by thermal expansion of the holding roll can be suppressed.

図１は本発明による実施例の裁断装置１を示している。この裁断装置１は吸収性物品帯状体を複数の裁断済み部分に裁断するためのものである。本発明による実施例では裁断済み部分は吸収性物品及びトリムからなり、すなわち帯状体が吸収性物品及びトリムに裁断され、分割される。ここで、吸収性物品はトップシートと、バックシートと、これらトップシート及びバックシートの間に配置された吸収体とを具備し、例えば生理用ナプキン、パンティライナ、失禁パッド、おむつなどを含む。   FIG. 1 shows a cutting apparatus 1 according to an embodiment of the present invention. This cutting device 1 is for cutting an absorbent article strip into a plurality of cut portions. In an embodiment according to the present invention, the cut portion is composed of an absorbent article and a trim, that is, the strip is cut into the absorbent article and the trim and divided. Here, the absorbent article includes a top sheet, a back sheet, and an absorbent body disposed between the top sheet and the back sheet, and includes, for example, a sanitary napkin, a panty liner, an incontinence pad, and a diaper.

図１を参照すると、裁断装置１は鉛直方向に並べて配置されたカッタロール２及びアンビルロール３を具備する。これらカッタロール２及びアンビルロール３はそれぞれフレーム４に対し、ほぼ水平方向の回転軸線Ｌ，Ｍ周りに回転可能に支持されており、したがって互いにほぼ平行な回転軸線Ｌ，Ｍ回りに回転可能になっている。なお、カッタロール２及びアンビルロール３は駆動装置（図示しない）によって互いに逆方向に回転される。   Referring to FIG. 1, the cutting device 1 includes a cutter roll 2 and an anvil roll 3 arranged side by side in the vertical direction. The cutter roll 2 and the anvil roll 3 are supported by the frame 4 so as to be rotatable about rotation axes L and M in the substantially horizontal direction, and thus can be rotated about rotation axes L and M that are substantially parallel to each other. ing. The cutter roll 2 and the anvil roll 3 are rotated in opposite directions by a driving device (not shown).

カッタロール２は本体２ａ及び軸体２ｂを具備し、アンビルロール３も本体３ａ及び軸体３ｂを具備する。   The cutter roll 2 includes a main body 2a and a shaft body 2b, and the anvil roll 3 also includes a main body 3a and a shaft body 3b.

カッタロール２の本体２ａの両側にはフランジ２ｃが設けられ、これらフランジ２ｃはアンビルロール３の本体３ａの周面に接触する。また、本体２ａの周面２ｄには帯状体を裁断するための例えば一対の刃２ｅが設けられる。周面２ｄのうちこれら刃２ｅによって囲まれた領域には、裁断済み部分を一時的に保持するための保持領域２ｆが形成される。この保持領域２ｆ内には、例えば回転軸線Ｌに沿って整列された複数の周面ポート２ｇが形成される。   Flange 2c is provided on both sides of the main body 2a of the cutter roll 2, and these flanges 2c contact the peripheral surface of the main body 3a of the anvil roll 3. Further, for example, a pair of blades 2e for cutting the strip-like body is provided on the peripheral surface 2d of the main body 2a. A holding region 2f for temporarily holding the cut portion is formed in a region surrounded by these blades 2e in the peripheral surface 2d. In the holding region 2f, for example, a plurality of peripheral ports 2g aligned along the rotation axis L are formed.

また、図２及び図３に示されるように、カッタロール２の本体２ａの一側面２ｈには側面ポート２ｉが形成される。周面ポート２ｇ及び側面ポート２ｉは本体２ａ内を貫通する連通路２ｊによって互いに連結される。   As shown in FIGS. 2 and 3, a side port 2 i is formed on one side 2 h of the main body 2 a of the cutter roll 2. The peripheral surface port 2g and the side surface port 2i are connected to each other by a communication passage 2j that passes through the inside of the main body 2a.

再び図１を参照すると、カッタロール２の上方には、カッタロール２に保持されたトリムを回収するための回収装置５が配置される。この回収装置５は負圧源（図示しない）に接続される。また、カッタロール２の一側面２ｈに対面して正負圧マニホルド６が回転不能に配置される。   Referring to FIG. 1 again, a recovery device 5 for recovering the trim held by the cutter roll 2 is disposed above the cutter roll 2. The recovery device 5 is connected to a negative pressure source (not shown). Further, the positive / negative pressure manifold 6 is disposed so as not to rotate so as to face one side surface 2h of the cutter roll 2.

正負圧マニホルド６は図４に示されるように、中央を貫通する貫通孔６ａを具備し、したがってリング状をなしている。また、正負圧マニホルド６は、接続ポート６ｂを介して正圧源（図示しない）に常時接続される正圧室６ｃと、接続ポート６ｄを介して負圧源（図示しない）に常時接続される負圧室６ｅを具備する。更に、カッタロール２の一側面２ｈに対面する正負圧マニホルド６の一側面６ｆには、正圧室６ｃに連通する円弧状の正圧ポート６ｇと、負圧室６ｅに連通する円弧状の負圧ポート６ｈとが形成される。この場合、図３にも示されるように、正圧ポート６ｇ及び負圧ポート６ｈの回転軸線Ｌからの半径方向位置は互いにほぼ等しく、カッタロール２の側面ポート２ｉの回転軸線Ｌからの半径方向位置ともほぼ等しい。   As shown in FIG. 4, the positive / negative pressure manifold 6 includes a through hole 6 a penetrating the center, and thus has a ring shape. The positive / negative pressure manifold 6 is always connected to a positive pressure chamber 6c that is always connected to a positive pressure source (not shown) via a connection port 6b, and to a negative pressure source (not shown) via a connection port 6d. A negative pressure chamber 6e is provided. Further, on one side surface 6f of the positive / negative pressure manifold 6 facing the one side surface 2h of the cutter roll 2, an arc-shaped positive pressure port 6g communicating with the positive pressure chamber 6c and an arc-shaped negative pressure communicating with the negative pressure chamber 6e are provided. A pressure port 6h is formed. In this case, as also shown in FIG. 3, the radial positions of the positive pressure port 6g and the negative pressure port 6h from the rotational axis L are substantially equal to each other, and the radial direction from the rotational axis L of the side port 2i of the cutter roll 2 The position is almost equal.

カッタロール２が回転して側面ポート２ｉが負圧ポート６ｈと対面すると、側面ポート２ｉが負圧ポート６ｈに連通して負圧室６ｅ内の負圧が周面ポート２ｇに印加される。同様に、側面ポート２ｉが正圧ポート６ｇと対面すると、側面ポート２ｉが正圧ポート６ｇに連通して正圧室６ｃ内の正圧が周面ポート２ｇに印加される。一方、カッタロール２が更に回転して側面ポート２ｉが負圧ポート６ｈと対面しなくなると、側面ポート２ｉは負圧ポート６ｈから遮断される。同様に、側面ポート２ｉが正圧ポート６ｇと対面しなくなると、側面ポート２ｉは正圧ポート６ｇから遮断される。このように、カッタロール２が回転することによって側面ポート２ｉと負圧ポート６ｈ及び正圧ポート６ｇとの連通及び遮断が切り換えられる。   When the cutter roll 2 rotates and the side surface port 2i faces the negative pressure port 6h, the side surface port 2i communicates with the negative pressure port 6h, and the negative pressure in the negative pressure chamber 6e is applied to the peripheral surface port 2g. Similarly, when the side surface port 2i faces the positive pressure port 6g, the side surface port 2i communicates with the positive pressure port 6g, and the positive pressure in the positive pressure chamber 6c is applied to the peripheral surface port 2g. On the other hand, when the cutter roll 2 further rotates and the side port 2i does not face the negative pressure port 6h, the side port 2i is blocked from the negative pressure port 6h. Similarly, when the side surface port 2i does not face the positive pressure port 6g, the side surface port 2i is blocked from the positive pressure port 6g. In this way, the communication between the side port 2i, the negative pressure port 6h, and the positive pressure port 6g and the blocking thereof are switched by the rotation of the cutter roll 2.

本発明による実施例では、図３からもわかるように、保持領域２ｆがアンビルロール３に対面してから回収装置５に到達するまでの回転角範囲内で側面ポート２ｉが対面するように負圧ポート６ｈが形成される。また、保持領域２ｆが回収装置５に対面している回転角範囲内において側面ポート２ｉが対面するように正圧ポート６ｇが形成される。   In the embodiment according to the present invention, as can be seen from FIG. 3, the negative pressure is applied so that the side port 2 i faces within the rotation angle range from when the holding region 2 f faces the anvil roll 3 until it reaches the collection device 5. Port 6h is formed. Further, the positive pressure port 6g is formed so that the side surface port 2i faces in the rotation angle range where the holding region 2f faces the recovery device 5.

図５に示されるように、カッタロール２の一側面２ｈと正負圧マニホルド６の一側面６ｆとの間にわずかばかりの間隙７が形成されるように、正負圧マニホルド６が固定される。すなわち、カッタロール２及び正負圧マニホルド６は互いに接触しない。なお、図５に示される実施例では、一側面２ｈ及び一側面６ｆは共に平坦である。   As shown in FIG. 5, the positive / negative pressure manifold 6 is fixed so that a slight gap 7 is formed between one side 2 h of the cutter roll 2 and one side 6 f of the positive / negative pressure manifold 6. That is, the cutter roll 2 and the positive / negative pressure manifold 6 do not contact each other. In the embodiment shown in FIG. 5, the one side surface 2h and the one side surface 6f are both flat.

図６に示されるように、フレーム４には筒状部分８ａを有するリング状の固定部材８が固定されている。正負圧マニホルド６は筒状部分８ａ周りに配置され、ネジ８ｂによって筒状部分８ａに固定される。カッタロール２の軸体２ｂは正負圧マニホルド６の貫通孔６ａ及び固定部材８の貫通孔を貫通してフレーム４に支持される。   As shown in FIG. 6, a ring-shaped fixing member 8 having a cylindrical portion 8 a is fixed to the frame 4. The positive / negative pressure manifold 6 is disposed around the cylindrical portion 8a and is fixed to the cylindrical portion 8a by screws 8b. The shaft body 2 b of the cutter roll 2 is supported by the frame 4 through the through hole 6 a of the positive / negative pressure manifold 6 and the through hole of the fixing member 8.

この場合、正負圧マニホルド６の固定部材８に対する位置は回転軸線Ｌ方向に調節することができ、したがって間隙７の大きさを調節することができる。   In this case, the position of the positive / negative pressure manifold 6 with respect to the fixing member 8 can be adjusted in the direction of the rotation axis L, and therefore the size of the gap 7 can be adjusted.

さて、吸収性物品帯状体はコンベアによってほぼ水平方向に移送され、裁断装置１、具体的にはカッタロール２とアンビルロール３との間に供給される。カッタロール２が回転して刃２ｅが帯状体に到達すると、図７に示されるように帯状体が吸収性物品Ａ及びトリムＴに裁断される。吸収性物品Ａは次いでコンベア（図示しない）によってほぼ水平方向に更に移送される。   Now, the absorbent article strip is transferred in a substantially horizontal direction by a conveyor and supplied between the cutting device 1, specifically, the cutter roll 2 and the anvil roll 3. When the cutter roll 2 rotates and the blade 2e reaches the belt-like body, the belt-like body is cut into the absorbent article A and the trim T as shown in FIG. The absorbent article A is then further transferred in a substantially horizontal direction by a conveyor (not shown).

一方、帯状体が裁断されるときにカッタロール２の側面ポート２ｉは正負圧マニホルド６の負圧ポート６ｈに連通している（図３参照）。したがって、このとき周面ポート２ｇには負圧が印加されており、この負圧ないし吸引力でもってトリムＴがカッタロール２の保持領域２ｆに保持される。カッタロール２が更に回転することによってトリムＴが回収装置５に向けて移送される。保持領域２ｆが回収装置５に到ると、側面ポート２ｉが負圧ポート６ｈから遮断され、しかしながら正圧ポート６ｇに連通し（図３参照）、したがって周面ポート２ｇに正圧が印加される。その結果、保持領域２ｆに保持されていたトリムＴが保持領域２ｆから離脱され、回収装置５の負圧ないし吸引力によって回収装置５内に回収される。   On the other hand, when the strip is cut, the side port 2i of the cutter roll 2 communicates with the negative pressure port 6h of the positive / negative pressure manifold 6 (see FIG. 3). Accordingly, a negative pressure is applied to the peripheral surface port 2g at this time, and the trim T is held in the holding region 2f of the cutter roll 2 by this negative pressure or suction force. As the cutter roll 2 further rotates, the trim T is transferred toward the collecting device 5. When the holding region 2f reaches the recovery device 5, the side port 2i is disconnected from the negative pressure port 6h, however, communicates with the positive pressure port 6g (see FIG. 3), and thus positive pressure is applied to the peripheral surface port 2g. . As a result, the trim T held in the holding region 2f is detached from the holding region 2f and is collected in the collecting device 5 by the negative pressure or suction force of the collecting device 5.

ここで、図５を参照して上述したように、カッタロール２と正負圧マニホルド６との間にはわずかばかりの間隙７が設けられる。このことは、正負圧マニホルド６との接触による摩擦熱が発生しないことを意味しており、したがってカッタロール２の熱膨張を確実に抑制することができる。   Here, as described above with reference to FIG. 5, a slight gap 7 is provided between the cutter roll 2 and the positive / negative pressure manifold 6. This means that frictional heat due to contact with the positive / negative pressure manifold 6 does not occur, and therefore thermal expansion of the cutter roll 2 can be reliably suppressed.

また、正圧ポート６ｇに印加される正圧及び負圧ポート６ｈに印加される負圧によって間隙７内に空気流れが生ずる。すなわち、正圧ポート６ｇから流出した空気が間隙７内を流れ、あるいは間隙７内の空気が負圧ポート６ｈ内に流入する。このため、この空気流れによってカッタロール２を冷却することができる。したがって、カッタロール２の熱膨張を更に抑制することができる。その結果、カッタロール２の熱膨張に起因する裁断不良を確実に抑制することができる。   In addition, an air flow is generated in the gap 7 by the positive pressure applied to the positive pressure port 6g and the negative pressure applied to the negative pressure port 6h. That is, the air flowing out from the positive pressure port 6g flows in the gap 7, or the air in the gap 7 flows into the negative pressure port 6h. For this reason, the cutter roll 2 can be cooled by this air flow. Therefore, the thermal expansion of the cutter roll 2 can be further suppressed. As a result, it is possible to reliably suppress cutting defects caused by the thermal expansion of the cutter roll 2.

ところで、間隙７に空気流れが生ずるということは正圧又は負圧の漏れが生じているということである。このため、周面ポート２ｇに印加される正圧又は負圧が弱められてトリムＴを確実に保持又は離脱できないおそれがある。したがって、間隙７に生ずる空気流れないし漏れを抑制する必要がある。   By the way, the fact that an air flow is generated in the gap 7 means that a positive pressure or negative pressure leak has occurred. For this reason, there is a possibility that the positive pressure or the negative pressure applied to the peripheral surface port 2g is weakened and the trim T cannot be securely held or detached. Therefore, it is necessary to suppress the air flow or leakage generated in the gap 7.

間隙７内の空気流れは例えば次のようにして抑制することができる。   The air flow in the gap 7 can be suppressed, for example, as follows.

図８（Ａ）及び８（Ｂ）に示される実施例では、正負圧マニホルド６の一側面６ｆに、カッタロール２の一側面２ｈに向けて突出するリング状の凸部９が形成される。凸部９は半径方向外側及び内側において正圧ポート６ｇ及び負圧ポート６ｈを囲むよう同心円状に延びている。その結果、間隙７内の空気流れを抑制することができる。なお、カッタロール２の一側面２ｈは平坦である。   In the embodiment shown in FIGS. 8A and 8B, a ring-shaped protrusion 9 that protrudes toward one side 2h of the cutter roll 2 is formed on one side 6f of the positive / negative pressure manifold 6. The convex portion 9 extends concentrically so as to surround the positive pressure port 6g and the negative pressure port 6h on the radially outer side and the inner side. As a result, the air flow in the gap 7 can be suppressed. Note that one side 2h of the cutter roll 2 is flat.

凸部９はリング状でなくてもよい。図９に示される実施例では、凸部９は正圧ポート６ｇ及び負圧ポート６ｈを囲むよう円弧状に延びている。また、正圧ポート６ｇと負圧ポート６ｈとの間に隔壁９ａが設けられる。この隔壁９ａは正圧ポート６ｇから間隙７を介し負圧ポート６ｈへの空気流れを抑制する。当然、凸部９又は隔壁９ａをカッタロール２の一側面２ｈに形成してもよい。   The convex part 9 may not be ring-shaped. In the embodiment shown in FIG. 9, the convex portion 9 extends in an arc shape so as to surround the positive pressure port 6g and the negative pressure port 6h. A partition wall 9a is provided between the positive pressure port 6g and the negative pressure port 6h. The partition wall 9a suppresses air flow from the positive pressure port 6g to the negative pressure port 6h via the gap 7. Naturally, the convex portion 9 or the partition wall 9a may be formed on one side surface 2h of the cutter roll 2.

図１０に示される実施例では、カッタロール２の一側面２ｈにリング状の凹部１０が形成され、凸部９が凹部１０内に受容される。図１１に示される実施例では、カッタロール２の一側面２ｈに凸部９と同様の凸部１１が形成され、正負圧マニホルド６の一側面６ｆに凹部１０と同様の凹部１２が形成され、凸部１１が凹部１２内に受容される。このようにすると、周面ポート２ｇに正圧又は負圧を更に確実に印加することができる。   In the embodiment shown in FIG. 10, a ring-shaped recess 10 is formed on one side 2 h of the cutter roll 2, and the protrusion 9 is received in the recess 10. In the embodiment shown in FIG. 11, a convex portion 11 similar to the convex portion 9 is formed on one side surface 2h of the cutter roll 2, and a concave portion 12 similar to the concave portion 10 is formed on one side surface 6f of the positive / negative pressure manifold 6. The convex portion 11 is received in the concave portion 12. In this way, positive pressure or negative pressure can be more reliably applied to the peripheral port 2g.

図１２に示される実施例では、正負圧マニホルド６の一側面６ｆに凸部９が形成され、カッタロール２の一側面２ｈに凸部１１が形成される。また、凸部１１の内側の一側面２ｈに画定された凹部１３内に凸部９が受容され、凸部９の外側の一側面６ｆに画定された凹部１４内に凸部１１が受容される。   In the embodiment shown in FIG. 12, a convex portion 9 is formed on one side surface 6 f of the positive / negative pressure manifold 6, and a convex portion 11 is formed on one side surface 2 h of the cutter roll 2. Further, the convex portion 9 is received in the concave portion 13 defined on the one side surface 2 h inside the convex portion 11, and the convex portion 11 is received in the concave portion 14 defined on the one side surface 6 f outside the convex portion 9. .

図１３に示される実施例では、正圧ポート６ｇ及び負圧ポート６ｈの半径方向位置が互いに異なっている。その上で、正圧ポート６ｇの半径方向外側、正圧ポート６ｇと負圧ポート６ｈとの間、負圧ポート６ｈの半径方向内側にリング状の凸部９がそれぞれ形成される。このようにすると、正圧ポート６ｇから負圧ポート６ｈへの空気流れも抑制される。なお、この場合、側面ポート２ｉは正圧ポート６ｇ及び負圧ポート６ｈの両方に連通し得るように寸法設定される。   In the embodiment shown in FIG. 13, the radial positions of the positive pressure port 6g and the negative pressure port 6h are different from each other. Then, ring-shaped convex portions 9 are respectively formed on the radially outer side of the positive pressure port 6g, between the positive pressure port 6g and the negative pressure port 6h, and on the radially inner side of the negative pressure port 6h. In this way, the air flow from the positive pressure port 6g to the negative pressure port 6h is also suppressed. In this case, the side surface port 2i is dimensioned so as to communicate with both the positive pressure port 6g and the negative pressure port 6h.

図１４に示される実施例では、正負圧マニホルド６の一側面６ｆの外周縁にリング状突起１５が形成され、カッタロール２の一側面２ｈの外周縁１６がこの突起１５によって囲まれる。このようにしても、間隙７内の空気流れを抑制できる。なお、突起１５はリング状でなくてもよく、例えば円弧状にすることができる。   In the embodiment shown in FIG. 14, a ring-shaped protrusion 15 is formed on the outer peripheral edge of one side surface 6 f of the positive / negative pressure manifold 6, and the outer peripheral edge 16 of one side surface 2 h of the cutter roll 2 is surrounded by the protrusion 15. Even in this case, the air flow in the gap 7 can be suppressed. In addition, the protrusion 15 does not need to be ring-shaped, and can be, for example, an arc shape.

図１５に示される実施例では、カッタロール２の一側面２ｈの外周縁１６にリング状の窪み１７が形成され、突起１５がこの窪み１７内に受容される。なお、カッタロール２のフランジ２ｃの側面に小径の円板部材を取り付けることによって窪み１７が形成されるようにしてもよい。この場合、円板部材の外周縁がカッタロール２の一側面２ｈの外周縁１６を構成する。   In the embodiment shown in FIG. 15, a ring-shaped recess 17 is formed on the outer peripheral edge 16 of one side 2 h of the cutter roll 2, and the protrusion 15 is received in the recess 17. In addition, you may make it form the hollow 17 by attaching a small diameter disc member to the side surface of the flange 2c of the cutter roll 2. FIG. In this case, the outer peripheral edge of the disc member constitutes the outer peripheral edge 16 of the one side surface 2 h of the cutter roll 2.

図１６に示される実施例では、カッタロール２の一側面２ｈの外周縁にリング状突起１８が形成され、正負圧マニホルド６の一側面６ｆの外周縁１９がこの突起１８によって囲まれる。   In the embodiment shown in FIG. 16, a ring-shaped protrusion 18 is formed on the outer peripheral edge of one side 2 h of the cutter roll 2, and the outer peripheral edge 19 of one side 6 f of the positive / negative pressure manifold 6 is surrounded by the protrusion 18.

これまで述べてきた本発明による各実施例では、トリムＴが互いに分離されている。しかしながら、帯状体から吸収性物品Ａを切り抜く場合には、トリムＴが帯状に連続することになる。この場合にも本発明を適用することができる。ただし、この場合には、刃２ｅの外周に保持領域２ｆが形成されることになる。   In each of the embodiments according to the invention described so far, the trims T are separated from one another. However, when the absorbent article A is cut out from the belt-like body, the trim T is continuous in the belt-like shape. In this case as well, the present invention can be applied. However, in this case, the holding region 2f is formed on the outer periphery of the blade 2e.

また、これまで述べてきた本発明による各実施例では、トリムＴはカッタロール２に保持される。しかしながら、トリムＴをアンビルロール３に保持するようにしてもよい。あるいは、吸収性物品Ａ及びトリムＴのうち一方をカッタロール２に保持し他方をアンビルロール３に保持するようにしてもよい。   In each of the embodiments according to the present invention described so far, the trim T is held by the cutter roll 2. However, the trim T may be held on the anvil roll 3. Alternatively, one of the absorbent article A and the trim T may be held on the cutter roll 2 and the other may be held on the anvil roll 3.

図１７は吸収性物品Ａをカッタロール２に保持しトリムＴをアンビルロール３に保持する場合を示している。すなわち、アンビルロール３の一側面に対面して正負圧マニホルド２０が固定される。アンビルロール３の周面にも保持領域２１が形成されており、保持領域２１内に形成された周面ポートに正負圧マニホルド２０から正圧又は負圧が印加される。この場合、互いに対面するアンビルロール３の一側面と正負圧マニホルド２０の一側面との間にわずかばかりの間隙を設けることができる。   FIG. 17 shows a case where the absorbent article A is held on the cutter roll 2 and the trim T is held on the anvil roll 3. That is, the positive / negative pressure manifold 20 is fixed facing one side surface of the anvil roll 3. A holding region 21 is also formed on the peripheral surface of the anvil roll 3, and a positive pressure or a negative pressure is applied from a positive / negative pressure manifold 20 to a peripheral port formed in the holding region 21. In this case, a slight gap can be provided between one side surface of the anvil roll 3 facing each other and one side surface of the positive / negative pressure manifold 20.

したがって、裁断済み部分を一時的に保持することが可能なロールを保持ロールと称すると、カッタロール２及びアンビルロール３のうち一方又は両方を保持ロールから構成しているということになる。その上で、互いに対面する保持ロールの一側面と正負圧マニホルドの一側面との間にわずかばかりの間隙が設けられるということになる。   Therefore, when a roll capable of temporarily holding the cut portion is referred to as a holding roll, one or both of the cutter roll 2 and the anvil roll 3 are constituted by the holding roll. In addition, a slight gap is provided between one side surface of the holding rolls facing each other and one side surface of the positive / negative pressure manifold.

更に、これまで述べてきた本発明による各実施例では、正負圧マニホルド６はリング状をなしている。しかしながら、図１８に示されるように、正負圧マニホルド６のうち正圧室６ｃ及び負圧室６ｅが設けられていない位置に、例えば扇状の切欠き６ｉを形成してもよい。このようにすると、カッタロール２の一側面６ｆが露出されるので、一側面６ｆからの放熱が促進される。また、正負圧マニホルド６の製造のための材料量が低減され、軽量化される。当然、正負圧マニホルド２０も同様に構成できる。   Further, in each of the embodiments according to the present invention described so far, the positive / negative pressure manifold 6 has a ring shape. However, as shown in FIG. 18, for example, a fan-shaped notch 6 i may be formed at a position in the positive / negative pressure manifold 6 where the positive pressure chamber 6 c and the negative pressure chamber 6 e are not provided. If it does in this way, since one side 6f of cutter roll 2 will be exposed, heat dissipation from one side 6f will be promoted. Further, the amount of material for manufacturing the positive / negative pressure manifold 6 is reduced and the weight is reduced. Of course, the positive / negative pressure manifold 20 can be similarly configured.

なお、これまで述べてきた本発明による各実施例を互いに組み合わせることもできる。例えば、正負圧マニホルド６の一側面６ｆに突起９を形成すると共に一側面６ｆの外周縁に突起１５を形成することができる。   The embodiments according to the present invention described so far can be combined with each other. For example, the protrusion 9 can be formed on one side surface 6f of the positive / negative pressure manifold 6 and the protrusion 15 can be formed on the outer peripheral edge of the one side surface 6f.
